Sy. Cheung et Mh. Ammar, USING DESTINATION SET GROUPING TO IMPROVE THE PERFORMANCE OF WINDOW-CONTROLLED MULTIPOINT CONNECTIONS, Computer communications, 19(8), 1996, pp. 723-736
In conventional multicast communication, the source carries a single c
onversation with all destination nodes. If a node on the path to any d
estination becomes congested, the throughput to all destinations is re
duced, thus treating some destination nodes unfairly. We consider a wi
ndow-controlled multipoint connection and study the use of destination
set grouping, where the destination set can be split into disjoint su
bgroups with the source carrying independent conversations with each s
ubgroup. We present a static grouping heuristic that can obtain near o
ptimum grouping for static network environments and a dynamic grouping
protocol which can adjust the grouping and the window sizes per group
in response to changing network conditions. The performance of the st
atic grouping heuristic and the dynamic grouping protocol are studied
using simulation and compared with single-group multicasting.
